Referring to fig. 1-6, a resonant leakage inductance transformer for a plate-type ozone generator according to some embodiments of the invention is described.

An embodiment of a first aspect of the present invention provides a resonant leakage inductance transformer for a plate ozone generator. In some embodiments of the present invention, as shown in fig. 1-6, the resonant leakage inductance transformer for a plate ozone generator includes:

the two insulating frameworks 1 are longitudinally arranged, and a primary coil 2 and a secondary coil 3 are circumferentially arranged on the insulating frameworks 1 respectively; the two insulating frameworks 1 are longitudinally butted and fixed.

The magnetic core 4, the magnetic core 4 includes a plurality of protruding portions, the protruding portions all extend along the longitudinal direction, and a plurality of protruding portions are arranged along horizontal single-column, and the protruding portions that are located in the middle along the arrangement direction longitudinally penetrate through the middle of two insulating frameworks 1 respectively.

The insulating mount 5, magnetic core 4 sets up inside insulating mount 5.

Wherein, the primary coil 2 and the secondary coil 3 are both of a multi-layer wound coil structure, and a ceramic tube 6 is inserted between adjacent layers of coils of the coil structure.

Specifically, three protruding portions of the magnetic core 4 are provided to form the E-shaped magnetic core 4.

The invention provides a resonant leakage inductance transformer for a plate-type ozone generator, wherein an insulating framework 1 provides structural support, the positions and the distances between a primary coil 2 and a secondary coil 3 are kept, and meanwhile, the insulation between the primary coil 2 and a magnetic core 4 is ensured; the insulating frame 1 is made of an insulating material, and current can be prevented from flowing directly through the insulating frame 1, thereby avoiding a short circuit and improving safety of the apparatus. The primary coil 2 receives an input voltage and generates a magnetic field, and the secondary coil 3 generates an output voltage under the influence of the magnetic field. According to the principle of electromagnetic induction, when an alternating current passes through the primary coil 2, a varying magnetic field is generated in the magnetic core 4, which in turn induces an electromotive force (voltage) in the secondary coil 3. The core 4 functions to provide a closed magnetic path to increase the magnetic flux, thereby improving the efficiency of the transformer, and the core 4 is composed of a plurality of protrusions arranged in a lateral direction and penetrating through the middle of the insulating bobbin 1 to form a closed magnetic path to effectively guide the magnetic field from the primary coil 2 to the secondary coil 3. The insulating holder 5 provides a stable mounting frame for the magnetic core 4 and ensures insulation of the magnetic core 4 from other components, the insulating holder 5 being generally made of a high-strength insulating material capable of withstanding mechanical stresses while not interfering with the magnetic circuit. The ceramic tube 6 is inserted between the coils of adjacent layers for increasing the insulation strength between the coils and preventing short circuit between the coils, and the ceramic is an insulating material with high strength and high temperature resistance, and can provide effective insulation under high voltage.

The primary coil 2 and the secondary coil 3 are wound on the insulating framework 1 (the insulating framework 1 comprises a high-voltage insulating framework and a low-voltage insulating framework), the magnetic cores 4 are aligned and other limiting structures, the magnetic cores 4 are not in direct contact with the primary coil 3 and the secondary coil 3, the central cylinder of the framework is circular, wire abrasion is reduced, and the external force is well buffered, namely, the shock resistance is good. The whole is fastened by the fastening bolts 502 through the upper insulating fixing plate 105 and the lower insulating fixing plate 105, the outside is not directly contacted with the magnetic core 4, a very simple winding process is provided, the materials are less, the cost is low, and the production efficiency is improved. The three protruding parts of the magnetic core 4 are layered with the insulating skeleton 1 and the winding wires, and the hollow ceramic tube 6 and the upper and lower insulating fastening plates 501 have higher thermal stability, so that the reliability and the safety are improved. The winding process is simple, and only the framework is needed to be fixed, and then the primary coil 2 and the secondary coil 3 are wound.

The insulating piece is used as a fastening structure, so that eddy current loss at the end part of the magnetic core 4 is reduced, and the safety coefficient is improved. Because the coils of the primary coil 2 and the secondary coil 3 are longitudinally wound in the wire winding grooves of the adjacent two insulating fixing frames 5 side by side, the distance is very short, independent inductors are not needed, the energy transmission efficiency is higher, and the winding process is simple.

In any of the above embodiments, the insulating skeleton 1 includes:

the limiting cylinder body 101, wherein the limiting cylinder body 101 is provided with a first axis, and the first axes of the limiting cylinder bodies 101 of the two insulating frameworks 1 are overlapped; any one of the stopper cylinders 101 is connected to a projection located at the middle in the arrangement direction to restrict the lateral movement between the core 4 and the insulating frame 1.

A plurality of long hollow end plates 102 are respectively arranged at the end parts of the limiting cylinder 101; at the end of each stopper cylinder 101, a long hollow end plate 102 is disposed circumferentially along the first axis. Wherein, the long hollow end plate 102 is longitudinally provided with a hollow hole 103, and the two insulating frameworks 1 are fixedly assembled through the longitudinally corresponding hollow holes 103.

In this embodiment, the function of the limiting cylinder 101 is to ensure the relative position between the core 4 and the insulating skeleton 1, limiting the lateral movement between them, which is critical for the correct formation of the magnetic field and for maintaining the electromagnetic characteristics; the limiting cylinder 101 is connected to the protruding portion of the magnetic core 4, since the first axes of the two are coincident, so that the magnetic core 4 is prevented from moving or dislocating laterally under the action of electromagnetic force or in mechanical vibration. At the end of the containment cylinder 101 are long hollow end plates 102, typically a plurality, arranged circumferentially along a first axis, for supporting and fixing the insulating framework 1, maintaining structural integrity; the long hollow end plate 102 is connected to the insulating frame 1 through a hollow hole 103. This design not only increases the overall stability of the structure, but also allows for increased design flexibility by allowing wires or other connectors to pass through because the holes are hollow.

As can be seen from the above, by precisely restricting the position of the magnetic core 4, the formation of the magnetic field can be controlled more accurately, and the performance of the electromagnetic device can be improved; when the electromagnetic device is operated, the magnetic core 4 and the insulating framework 1 are prevented from being shifted due to mechanical vibration or thermal expansion, so that long-term stable operation of the equipment is ensured; the hollow hole 103 provides a simple fixed assembly method, and is convenient for disassembly and assembly during manufacture and maintenance; the insulating framework 1 is fixed through the hollow hole 103, so that the direct contact of metal parts is avoided, and the electrical insulation property is maintained; the structural design can be adjusted according to different electromagnetic equipment requirements, and diversified application requirements are met.

By longitudinally butting and overlapping the first axes of the two limiting cylinders 101, the two limiting cylinders 101 are longitudinally aligned and are better fixed, and the long hollow end plate 102 can fix the limiting cylinders 101 and limit coils.

In any of the embodiments, the outer wall of the limiting cylinder 101 is provided with the grooves 104 along the first axis direction, and the grooves 104 are disposed in plurality along the circumferential direction of the limiting cylinder 101.

Wherein the grooves 104 are located between circumferentially adjacent long hollow end plates 102 in the first axial direction.

In this embodiment, the groove 104 is typically used to reduce the mass of the structure, provide additional flexibility, or be used to mount other components such as seals, clamps, or wires; in electromagnetic applications, the grooves 104 may be used to alter the magnetic field distribution or provide space for placement of insulating material, thereby reducing leakage from the core 4 portion and improving overall electromagnetic performance; the grooves 104 may also be part of a thermal management system that allows air to flow to dissipate heat generated by the magnetic core 4.

By providing the stopper cylinder 101 with the groove 104, the mass thereof can be reduced without sacrificing its structural integrity, which is particularly important for applications requiring precise control of the mass thereof. The grooves 104 may also provide some resiliency to help absorb shock and impact; the grooves 104 can be used for optimizing the magnetic field distribution and reducing unnecessary magnetic loss by changing the geometric shape of the magnetic core 4 so as to influence the magnetic resistance; if insulating material is placed in the grooves 104, the path of the current can be further isolated or directed, improving the safety of the device. The grooves 104 may also increase the heat dissipation efficiency of the core 4, as they allow air to flow, thereby helping to dissipate heat.

The grooves 104 are located between circumferentially adjacent long hollow end plates 102, which allows them to act as connection points for the two end plates, providing additional mechanical support while reducing the use of materials.

The groove 104 is formed in the outer wall of the limiting cylinder 101, so that the roughness of the outer wall can be increased, the winding of the coil is facilitated, a plurality of coils are arranged in the circumferential direction, stable winding of the coil is guaranteed, and as the primary coil 2 and the secondary coil 3 have heat generation in operation, the groove 104 is formed and longitudinally located between the adjacent long hollow end plates 102, so that the heat generated in the groove 104 is brought out along the groove 104 by air flowing through the outside, and heat dissipation of the groove 104 by the long hollow end plates 102 is prevented from being blocked.

In any of the above embodiments, the ceramic tube 6 is provided in plurality in the circumferential direction between adjacent layers of coils of the coil structure, and the ceramic tube 6 is provided corresponding to the groove 104 in the preset direction.

The preset direction is vertical and points to the direction of the first axis.

In this embodiment the ceramic tube 6 is mainly used to provide insulation, preventing electrical shorting between the electromagnetic coils. In the multilayer coil structure, ceramic tubes 6 are inserted between adjacent layers, so that the insulation distance between the layers is increased, and the voltage withstand level of the whole coil is improved. The ceramic tube 6 may also provide mechanical support to some extent, enhancing the overall structural stability of the coil. Ceramic is a high strength, high insulation material that can operate in high temperature and high pressure environments without damage. The use of the ceramic tube 6 reduces the breakdown phenomena between coils that may be caused by the large electric field strength.

The ceramic tube 6 is disposed in a predetermined direction corresponding to the groove 104, so that the space provided by the groove 104 is used to place the ceramic tube 6, thereby effectively utilizing the inner space without increasing the outer size. At the same time, this design is designed to optimize the internal heat dissipation path. The grooves 104 allow air flow and the placement of the ceramic tubes 6 may help to direct heat movement from the hot spot areas to the groove 104 areas, thereby improving heat dissipation efficiency. The predetermined direction is a vertical direction pointing towards the first axis, which is usually to coincide with the direction of the core 4. The vertically placed ceramic tube 6 can have minimal impact on the distribution of the magnetic field while maintaining its insulating properties.

The ceramic tube 6 can support the coil and increase insulating heat dissipation, the ceramic tube 6 and the groove 104 are correspondingly arranged, so that the layer-by-layer arrangement of the coil is more stable, the outer coil is extruded into the inner coil, and the ceramic tube 6 is extruded to the position corresponding to the circumference of the inner coil, so that clamping position fixing is realized.

In any of the above embodiments, the ceramic tube 6 has a second axis, and the ceramic tube 6 is provided with a through hole along the second axis.

Wherein the second axis is parallel to the first axis.

In this embodiment, the through holes function as heat dissipation holes having a heat dissipation function in the ceramic tube 6. The heat sink holes allow air to circulate, which helps to dissipate heat generated by the current during operation. Such ventilation may reduce the overall temperature of the device, preventing performance degradation or damage due to overheating.

In a multi-layer coil structure, the heat dissipation holes can also help heat transfer from the interior of the coil to the external environment, avoiding heat accumulation inside; the second axis is parallel to the first axis, ensuring that the heat dissipation holes can be directly conducted in the length direction of the whole ceramic tube 6. Such even distribution helps to achieve more efficient thermal management.

The design of the heat dissipation holes is based on the principles of heat conduction and convection. Heat is conducted through the material of the ceramic tube 6 to the heat sink holes and as air flows through these holes, heat is carried away, achieving convective heat dissipation. Although heat dissipation holes are provided, the design ensures that the structural integrity of the ceramic tube 6 is not affected. The ceramic tube 6 needs to maintain sufficient mechanical strength so as not to break during assembly and operation. Even if heat radiation holes are opened in the ceramic tube 6, these holes do not deteriorate the performance as an insulator due to the high insulation of the ceramic itself. Ceramic materials are capable of withstanding high temperatures without sacrificing insulation.

The ceramic tube 6 is provided with a through hole along the second axis, so that more heat dissipation means can be provided for the primary coil 2 and the secondary coil 3 in the longitudinal direction.

In any of the above embodiments, the inner layer coil of the adjacent layer coil of the coil structure and the ceramic tube 6 inserted in the current adjacent layer coil have a first bonding area, and the outer layer coil of the adjacent layer coil of the coil structure and the ceramic tube 6 inserted in the current adjacent layer coil have a second bonding area.

The first bonding area is larger than the second bonding area.

In this embodiment, providing different thermal contact areas may correspond to different heat dissipation requirements. Since the inner coil may be more difficult to dissipate heat, providing a larger bonding area may increase its thermal contact with the ceramic tube 6, thereby improving heat dissipation efficiency. In electromagnetic designs, the inner coil is closer to the core 4, and thus there may be a higher current density and more heat generation. Thus, increasing the contact area with the ceramic tube 6 facilitates heat transfer. The first bonding area (bonding area of the inner layer coil) is larger than the second bonding area (bonding area of the outer layer coil), which makes the inner layer coil have a larger contact surface with the ceramic tube 6, and can achieve better heat conduction. The greater the contact area, the greater the efficiency of heat transfer, as heat is transferred from the hotter to the colder regions. Thus, increasing the contact area of the inner coil with the ceramic tube 6 may increase the rate of heat transfer from the coil to the ceramic tube 6.

The inner coil, due to its close proximity to the core 4, has a high magnetic field strength and possibly a high current density, resulting in more heat generation. By increasing the contact area, the heat can be more effectively dispersed, reducing the formation of hot spots.

The ceramic tube 6 not only performs a heat dissipation function, but also provides mechanical support. The larger contact area of the inner coil with the ceramic tube 6 helps to increase structural stability against mechanical stresses due to thermal expansion and the like.

Through in the coiling, with the first laminating area of inlayer coil with insert the ceramic pipe 6 of establishing at present adjacent layer coil be greater than the outer coil with insert the second laminating area of establishing at the ceramic pipe 6 of present adjacent layer coil, can make the degree that two coil lines of laminating of ceramic pipe 6 oppress ceramic pipe 6 different, guarantee that more forces are exerted to the coil of inner circle, guarantee holistic coiling stability.

In any of the above embodiments, the outer walls of the inner layer coil and the outer layer coil in the adjacent layer coils of the coil structure and the outer wall of the ceramic tube 6 form a heat dissipation cavity, and the upper end and the lower end of the heat dissipation cavity are provided with heat dissipation openings.

In this embodiment, the heat dissipation chamber provides a space that allows air to flow, which helps transfer the heat generated by the coil to the external environment. When air flows in the heat dissipation cavity, heat is taken away, and the temperature of the coil is reduced through convection. The upper and lower ends of the heat dissipation chamber are provided with heat dissipation openings which allow air to enter and leave the heat dissipation chamber. The heat dissipation ports can be naturally ventilated or used with forced cooling devices such as fans to promote air circulation.

Thermal convection refers to the process of carrying heat as a fluid (in this case air) moves. As air flows through the heat dissipation chamber, it will absorb heat and expel it from the heat dissipation port, thereby cooling the coil. When the air in the heat dissipation chamber is heated, it expands and rises, while the cooler air sinks. This cyclic process of thermal expansion and sinking promotes air flow and enhances heat dissipation. Heat may be transferred from the coil to the air of the heat dissipation chamber by radiation and conduction. The design of the heat dissipation chamber makes these processes more efficient because they provide a larger surface area and more air flow to dissipate heat. The thermal gradient (i.e., temperature differential) is the motive force that pushes heat from a high temperature region to a low temperature region. The temperature difference between the inside of the heat dissipation cavity and the external environment promotes heat to flow through the heat dissipation opening, so that heat dissipation is realized.

The heat dissipation cavities are formed through the outer walls of the inner coil and the outer wall of the ceramic tube 6 so as to directly dissipate heat emitted between the adjacent coils, thereby ensuring the overall heat stability of the device and finally being discharged through the heat dissipation cavities through the heat dissipation openings at the upper end and the lower end by means of non-flowing air.

In any of the above embodiments, each layer of the coil except the outermost layer in the coil structure forms a bent portion around the ceramic tube 6.

The bends formed by the innermost coils in the coil structure are located within the grooves 104.

In this embodiment, the bend of the coil changes the shape and size of the coil in electromagnetic applications, thereby adjusting its inductance value and magnetic field distribution. The bending part is also favorable for fixing the coil in place, so that the influence of vibration on the position of the coil is reduced, and the stability of the whole structure is improved. Providing the bent portion of the innermost coil within the groove 104 may provide additional fixation points that reduce movement of the coil during operation. In addition, the grooves 104 provide physical space for the bent portions, and can prevent the coils from being pressed or worn out, thereby reducing the risk of insulation damage.

The shape and size of the coil have a significant impact on its electromagnetic properties. The addition of the bent portion changes the current path, thereby affecting the self-inductance and mutual inductance characteristics of the coil. By precisely controlling the shape and the position of the bending part, the electromagnetic field of the coil can be optimized to be more concentrated or dispersed so as to meet specific electromagnetic performance requirements.

The presence of the bends increases the structural integrity of the coil, as they can resist shape deformation caused by temperature changes, vibration or mechanical shock. The placement of the bends in the grooves 104 ensures that the coil remains stable under mechanical stress, especially during long operation or in harsh environments. The bent portion is located in the groove 104, and the groove 104 may serve as a heat dissipation channel to help guide heat generated by the coil current to an external heat dissipation cavity or heat dissipation hole. The ceramic tube 6 can help to disperse heat and prevent local overheating due to the good thermal stability of the ceramic.

The bending parts are formed so as to form a plurality of coil parts in a bending state which are circumferentially arranged in the coil structure, the transverse shaking of the coil can be limited through the bending parts, the coil is prevented from being scattered, the integral stability of long-term use is ensured, and the bending parts of the innermost layer are arranged in the grooves 104 so as to strengthen the integral sleeving firmness of the insulating framework 1, the primary coil 2 and the secondary coil 3.

In any of the above embodiments, the insulating holder 5 includes:

two insulating fastening plates 501 are provided, and two insulating bobbins 1 are each longitudinally located between the two insulating fastening plates 501.

A plurality of fastening bolts 502 are provided along the circumference of the insulating frame 1 for connecting the two insulating fastening plates 501.

In this embodiment, the insulating fastening boards 501 provide a stable and protective platform for the insulating framework 1, so that it is fixed between the two insulating fastening boards 501 in the longitudinal direction, ensuring that the insulating framework is not displaced by external forces such as vibration or impact. The insulating fastening plate 501 also isolates the electrical parts from short circuits or electrical shocks caused by current passing through the insulating skeleton 1. The fastening pegs 502 serve to fasten and connect two insulating fastening plates 501 together, thereby providing additional mechanical stability between the two insulating frameworks 1. The design of the insulating frameworks allows a certain adjusting space between the insulating frameworks, and the pressure or the position of the insulating frameworks can be adjusted according to actual needs.

The fastening plate made of the electrical insulating material can effectively isolate current, prevent electrical faults and ensure safe isolation among components. The use of a plurality of tie bolts 502 in the design is distributed around the insulating framework 1, and such distribution helps to evenly distribute mechanical stresses due to handling or the external environment, protecting the insulating framework from damage. The different coefficients of expansion of the insulating material and the metal component during a temperature change, the design of the fastening peg 502 allows for some elasticity so that structural integrity can be maintained during a temperature change.

Screw holes are formed in the corresponding longitudinal positions of the two insulating fastening plates 501 so as to facilitate screwing of the fastening bolts 502, complete integral fixation of the insulating fixing frame 5, and the fastening bolts 502 protrude from the insulating fastening plates 501 so that the extending parts can be screwed and fixed with the outside, thus completing fixation of the device and avoiding additional fixation structures.

In any of the above embodiments, the opposite surfaces of the two insulating fastening plates 501 are respectively provided with the positioning grooves 5011, and the magnetic core 4 includes the connecting portion for connecting the plurality of protruding portions.

One end of the protruding portion away from the connecting portion and the connecting portion respectively abut against the positioning groove 5011.

In this embodiment, the positioning groove 5011 is used to receive the protruding portion and the connecting portion of the magnetic core 4 to fix the magnetic core 4 in a predetermined position. In this way, the detent 5011 reduces movement or vibration of the core 4 during operation, improving the stability of the device. The core 4 is composed of a plurality of protruding parts connected by connecting parts to form a complete magnetic circuit. The design of the protrusions helps to concentrate the magnetic field, while the connection ensures an efficient transfer of the magnetic field between the parts of the core.

The positioning grooves 5011 are precisely machined on the insulating fastening plate to ensure that the protruding portions and the connecting portions of the magnetic core 4 correspond thereto, which helps to ensure the accurate position of the magnetic core 4 during assembly. This precise mechanical abutment ensures the stability of the core 4 in its operating environment, avoiding the electromagnetic properties being affected by the positional offset.
